This invention relates to machines for use in the placing or depositing in envelopes or similar containers of currency which may consist of both notes or bills and coins in required amounts for the purpose of paying oif anumber of employes at the end of a day, Week or other period of time, or at any time, or for any purpose. f

The general purpose of the invention is to provide a machine which may be employed efficiently for the purpose indicated, thereby enabling the avoidance of the laborious task of filling such envelopes or other containers manually.

One form of machine (which is illustrated in the accompanying drawings) embodying my invention comprises two units. One of these unitsis provided with a plurality of A separate means for holding notes or bills of different denominations or values and with means whereby one or more bills or notes may be extracted or withdrawn from any holder or from a plurality of holders. The other of said units comprises holding means for coins of different denominations or values. The coins necessary to make up any sum may be selected from these holders or containers.

The latter unit also contains holding means for the envelopes to be lled. The operation of both the note extracting or selecting means and the means for selecting and releasing coins from their holding meansiseffecte by means the operation of which is controlled by the passage of the envelopes through the second named unit. The bills or notes, the

coins andthe envelopes are conveyed to a common or central point of the machine Where means is provided for effecting the placing or depositing of the currency in the o envelopes in the dierent amounts which may have been selected, the said amounts being controlled by the passageof the envelopes through the second named unit of the machine', which envelopes are provided with` means to control the mechanism for selecting v the bills or notes and the coins. L The invention in its broadest aspect has for its object to provide a machine of novel construction having means whereb the required amounts may be placed or eposited 1926. Serial No. 105,751.

in successive envelopes or containers as and when the latter arrive at a predetermined selected point in the machine.

It is also an object of the invention to provide a machine having novel means whereby 'one or more bills or notes may be selected from any one of a number of piles of bills or notes supported in containers, the bills or notes in the diiferent containers being of diiferent denominations or values.

It is also-an object of the invention to provide means for conveying the said bills or notes, after selection, to a predetermined point and to fold the same during their passage to such point into a form to facilitate their insertion into envelopes.

Another object of the invention is to provide means whereby the required coins may be selected from a plurality of holders or containers, each holder or container having therein a coin of different denomination or value, and thereafter depositing the same in the same envelope with the bills or notes referredl to in the previous paragraph, so as to make up the required amount which is to be placed in such envelope.

A further object ofthe invention is to provide means Whereby'the selection of the required bills or notes and coins shall be controlled by the passage of the envelopes into position to receive the bills or notes and the coins so selected and which are necessary to make up the amount which it isdesired to place within such envelope.

The foregoing sets forth in a general way the objects of my invention, but other ob# jects and advantages of the invention will be pointed out in the detailed description thereof which follows or will be apparent from such description. l

In order that the invention may be more easily understood and a ull comprehension of its advantages more readily acquired reference may be had to the accompanying drawings in which I have illustrated one form of machine embodying the principle of the" said invention.

Tm: GENERAL CoNs'rRUcrIoN AND OPERATION Before proceeding with a description in detail of the above figures of the drawings depicting a machine embodying the invention I shall describe somewhat generally' the machine and its operation.

In the usual case the machines will each be provided with five bill or note holders 7, the said holders respectively holding notes or bills of different denominations, as already indicated. The bills or notes are stacked flat `in therespective holders. From the respectivelholde'rs 7 they are drawn one at a time into contact with rotating bill or note collecting cylinders 22. If the bills or notes of a holder are released one bill or note is drawn therefrom for each revolution of the c linder associated with'the said holder.` If t e bills or notes of a holder' are not released, the collectinflr cylinder associated therewith revolves idly. When the end of a bill or note reaches a c linder 22 it is immediately clamped to t e ripher` thereof in a manner similar to t at 1n w 'ch a sheet is held upon the cylinder of a rotary printing press. One -bill or note maybe drawn from each holder or container, or a plurality of bills or notes ma be drawn successively-from one or more ho ders or containers, or notes or l y bills may be drawn from some Vof the containers and not from the others'depending u on vthe punchin'gof the envelgpes Yfinto which the currencyis yto`be deposited. As already indicated, the envelopes are provided with means whereby the mechanism for se-l v lectinglthe bills ornotes is controlled.

lDuring the operation ofthe machine and after the bills or notes as required have been collected upon the collecting cylinders 22the rotation or revolution of the said cylinders is interrupted in such position that the middle 4 lines of the bills or notes thereupon are located in the same horizontal plane, which plane is located intermediate the guides 72 and 73, between which the bills are carried from thel left toward the right (having reference to Fig. l) to the semi-circular guides 74 and 7 5. The bills or notes are removed from the collecting cylinders 22 and are carried or conveyed forwardly by a sweep or plunger 98. The guides 72 and 73 are provided with arcshaped extensions which project in opposite directions from positions in adjacent relation to the collecting cylinders 22, which projections are spaced from and partially encircle or surround the cylinders 22 to form annular guiding chambers or passageways. The collecting cylinders 22 are rovided wlth diametral slots which, when t e revolutions ot' said cylinders are interrupted to'permit the removal of bills or notes therefromby the plunger or sweep 98, occupy positions in the horizontal plane, previously referred to.

It will be seen, therefore, that by the means described, and as shown in Fig. 1, a free passageway between and through the collecting cylinders is provided, as well as around the same. As the plunger or sweep 98 travels through the horizontal passageway, between the guides 72 and 73, it engages any bills or notes which may be carried upon the surfaces of the collecting cylinders 22, folds the same and conveys vthem forwardly to theright.

hand end of the Said passageway. VThe bills or notes are folded in the middle.

After the plunger or sweep 98 has reached the end of its movement toward the right to convey folded bills or notes into position extending across the passageway between the arc-shaped guides 74 and 75 itis returned by suitable mechanism alon the'dotted lines a to its initial position at t e left hand side of the bill or note feeding unit of the machine, as indicated in Fig. 1. The operations of strippingr or removing the bills or notes from the collecting cylinders 22 by the plunger or sweep 98 and the returning of the latter to its initial position are repeated one after another until the operation of the machine is discontinued. v

. The guides 72 and 73 are connected at their right hand end so as to form a closed ocket 72. This closed endis located in a jacent relation to and beyond the guides 74 and 75. The passageway formed by the guides 74 and 75 is in communication with and intersects or crosses the passageway formed by the guides 72 and`73. 'After one or more `fielded bills have been carried into position llt) in a pocket 202 of the lenvelope filling and p discharge unit.

By reference to Fig. 2 it lwill'be seen that end portions in a box like member 206 as shownin Figs. 39 and 44 and as will bedescribed hereinafter in more detail, having reference to Fig.,2 of the drawings, while the remaining portions thereof are free. The

blade 204 is shorter thanthe blade 203 and is bent downward at its right hand end, having reference to Fig. 2 of the drawings, nearly into contact with the said blade 203. The

,latter'is bent upward slightly at its right hand end, as is clearly indicated iny Figs. 2

. and 44.

The envelopes are piled or stacked in a bin f or holder 224 with the open ends thereof facing toward the feed rollers 239. From the bin or holder 224 the envelopes are fed forwardly through the envelope feeding unit of r the machine toward a central delivery point in adjacent relation to the pocket 202, previously referred to. The passage of the en-l velopes throu h .the machine controlls the operation of t e note` selecting mechanism, previously referred to. As the envelopes are carried forward theV `slightly protruding lower li s thereof contact with the right han end of t e lower blade 203 and are depressed, which causes the upper` lips of the envelopes to rise. During the further movement of an envelope, under the influence of the feeding rollers 239, it is opened and thrust upon the blades 203, 204 ,and 205 upon which it is held by friction. The blades 203, 204 and 205 are top,

mounted upon a carrier orsupport 206 (Fig. 44) which is rotatable through an angle of 90. When so rotatedan envelope which may be mounted thereon`is caused to assume a vertical position with the o en end at the as indicated by the dotte lines immediatel above the 'vertical guides 269 and 270, as s own in Fig. 2 of the drawings. While in this sition coins previously released from thelr respective holders are released and are delivered thereinto from a nozzle 352 of the coin distributing apparatus. Entrance of the coins into the envelopes is facilitated by the presence of the blade 205 mounted upon the blade 204. The relation of these two blades to each other is such as to effect opening yof the envelopes in a manner to form a clear space or opening through which' the coins may enter.

The guides 269 and 270, reviously referred to, which are arrange in pairs engage the opposite edge portions of the envelopes which occupyvertical positions, as indicated in Fig. 2 of the drawings, during the filling operation and afterwards. After hav- `ing been filled the envelopes are pushed to the right, having reference to Fig. 2 of the drawings, along guides 279 by means of a plunger 273. The envelopes are maintained in vertical position by a movable block 283". The vertical envelopes and the block 283Il are moved alongl upon the said guides step by step under lthe influence of the plunger 273, previously referred to.

The coin delivery mechanism designated as a whole by the reference number 319 is provided with holders for fifty, twenty-live, ten, five and one cent pieces. The required coins are released as the holes in the envelopes register with electrical contacts which are located between the two intermediate pairs ofenvelope feedin rollers 239IL and 240* (shown in Fig. 2). Tliese rollers, together with other pairs of rollers, operate to feed the kenvelo es from the bin or holder 224 to the note poc et 202 and onto -the blades 203, 204, and v205, previousl referred to. Similar contacts are mounted etween the right hand two pairs of feeding rollers (having reference to Fig. 2 of in adjacent relation to the bin or holder 224. When the holes in the envelopes register with these contacts the circuits are closed which o erate to control the note releasing mechamsm, previously referred to. The mechanism o the envelope feeding unit of the machine is so arranged and so operates as to cause the envelopes to dwell after each operation of the releasing means of the bill or note releasing mechanism in order to properly time the arrival of the released notes to meet the envelopes and the coins atthe filling point so that the said bills or notes and coins may be inserted or deposited in the said envelopes.

The holes or perforations in the envelopes are arranged so as to complete the circuits for controlling the coin releasing mechanism and the bill or note releasing mechanism in a manner to release and deliver to the filling oint the amounts required for each enveope. The holes, as shown in the envelope which is illustrated in Fig. 4 of the drawings, are arran ed so as to release seventy-eight dollars ($8') in bills or notes and ninety-one cents (91e) in coins. Y

The general plan of the machineand its operation having been indicated I shall now proceed with a description of the respective groups of mechanism hereinbefore referred to in the order in which such mechanisms have meen mentioned.

l. Tm: Nora Commermo UNrr The note collecting unit 4of the machine comprises a frame having a basel (Figs. 4* to 7) upon which is mounted an upper frame divided into sections.' In the construction as illustrated only three sections are shown, which sections are identified by the numerals 2, 3 and 6, 2 and 6 designating the two end the drawings) 239 and 240, which are located sections and the numeral 3 the intermediate section. In the machine as actually constructa. The note magazines The holders or containers 7 for the bills or notes are mounted on bases 8 which are in turn fitted to or mounted upon ways or guides 9 arranged longit-udinally of the bill orv note shaft 20, it is apparent that the said holder` collecting unit along the top of the upper frames 2, 3 and 6, and, of course,alon the top of the additional upper interme iate frames referred to, but not shown. These ways are not continuous, but each of them is of suflicient length to permit the bin supported thereon to be moved back and forth a distance of several inches. Racks 10 which are attached to one side of the respective bill or note holders or containers 7 engage Agears 11 (Figs 11 to 14) mounted upon suction rollers 12. Horizontally disposed. levers 13 are mounted upon the upper frames of the bill or note collecting unit of the machine, previously referred to. One of these levers is associated with each ofthe sections of theupper frame and each is mounted at its middle upon a stationary pivot pin 14. One end of each lever is connected by means of a link 16 to a longitudinally extending coupling bar 15 (Figs. 6, 7 and 8) located at the u Vper edge of the rear side of the said unit, whi e the opposite end of each lever is connected by means of a short link 17 to the base 8 of one ofthe bill or note holders or containers, previously referred to. Upon oscillation of the leversv 13 reciprocating or back and forth movement vofthe bases 8 and thebill holders mounted thereon is` effected. Oscillation of the said levers is effected by a reciprocating movement V20 also drives -the collecting cylinders 22 through or by means of the helical gears 23 and 24 (Figs. Sand 12). The bill or note holders 7 and the collecting cylinders 22 having a common actuator, namely, the drive ma be caused to reciprocate rin' harmony wit and in roper correlation to the rotation of the sald collecting cylinders,

" 'a me mueca@ cylinder@ Upon reference to Fig. 8 of the drawings .it will be noted that each collecting cylinder one end only. The purpose of this is that means may be provided for permitting the free passage of the plun er or sweep blade, previously referred to,

have been released and removed from the bill or note holders and deposited upon the said cylinders. The rear end of each of the collecting cylinders 22 is provided with gear teeth 25 on :a pitch-circumference which conincides with the periphery of the c linder.

'The gears 25 are in mesh respective y with or removing fromv -the collecting cylinders bills or notes which the upper free end of a swin ng frame 29. l

Each of the said rollers 28 is eld'yieldingly against its associated feed roller 26 by the action of a flat spring 30 which is fixed or secured to the swinging frame 29. The res ctive rollers 28 are rotated by reason of t eir frictional engagement with the feed rollers with which they are associated; The pressure roller 28 is provided with a relatviely wide groove extending around the middle portion thereof in which runs a belt'28 Said belt extends over a pulley 29* mounted upon the arbor 30 of the swinging frame 29.

A bill or note which may be delivered to these rollers 26 and 28 of the respective bill or note feeding mechanisms is firmly held thereby and urged or fed forward onto the associated collecting cylinder 22. Located in operative relation to the respective collecting cylinders 22 .are gripper actuating cams 31 and 32 (Figs. 10 and 12). These cams are mounted on studs 33 and are driven by gears 34. The

respective gears are in engagement with theV teeth of the respective gears 25 of the collecting cylinders '22. The gripper cams 31 and 3.2 are alike and are set or located at an angle of 180 with respect to cach other. Y The number of teeth of the gear 34.- for rotating theV cams 31 and 32, b means of which the tappets 35 and 36, w ich are mounted radially' upon the collecting cylinders 221are operated,

is so chosenwith relation to t e number yof teeth upon the gear 25 that the said tappets engage the said cams alternately; that is to say, the cam 31 makes one revolution after contacting with or engaging the tappet 35.
